Which of the following is a method of land description used in Oregon?

In Oregon, all of the listed methods of land description are applicable. The metes and bounds system relies on physical features and measurements to describe land. This method can be particularly useful in irregularly shaped parcels, allowing for detailed delineation based on distances and directions.

The range and township method is part of the Public Land Survey System (PLSS) and is commonly used in many Western states, including Oregon. It divides lands into six-mile-square townships, which are then further divided into sections for more precise legal descriptions.

The rectangular survey system is essentially another term used to describe the range and township system. It provides a systematic approach to land description that began with the Land Ordinance of 1785 and is still in use today.

Because each method is valid and utilized within Oregon for different purposes—depending on the geographical context or the history of the land—they all collectively represent the correct answer in this context. Each system has its own advantages and is suited for different types of land transactions and descriptions.
